Need cam help for 340 Duster

The car is being bead blasted this coming week so I can see what sheet metal I need other than floors. This is a big project for me so I look for advice from you guys in here for parts, resources and just plain knowledge. Thanks for taking the time, I'm going to bring your info to the engine builder. And yes I'm planning on changing the 513's. I'm told the best time this car ran with that set up was an 11.91 @ 115 at Englishtown in 1982. I don't see myself or my son as a weekly racer but I do want to honor the history of the car and try to preserve the car the best I can. Thanks again!
